Full Rewire

Rewiring a home can be one of the most challenging investments a homeowner can face. New wiring must be installed in every room, and the current wiring is usually deep within the walls.

It’s recommended that the property be rewired every 25 years. This ensures that safe and modern cables are used, incorrectly installed electrics are fixed, and potential hazards like deteriorated cables are removed.

Full rewiring is necessary if you’re struggling with faulty wiring, a blown fuse, electric shocks, fuse board damage or any other electrical system troubles. When it comes to a full rewiring job, you can rest assured that our qualified electricians have the expertise to update your home wiring according to the latest certified wiring options.

Our comprehensive rewiring includes:

  • Testing and Fault Finding
  • A New Consumer Unit
  • Tidying New Channels
  • New High-Quality Wiring
  • Neatly Reapplying Plaster
  • Updated smoke alarms
  • Earth bonding

Partial Rewire


If your home has been rewired within the last 25 years and your cables can withstand current electrical loads, you will need partial rewiring. Partial rewires are an option if you need new earthing upgrades, bonding or a new electrical service panel upgrade and if you don’t have any faulty electrics.

Our partial rewiring services include the following:

  • Local Qualified and Experienced Electricians
  • Marking & Creating Channels for New Wiring
  • Installing Wiring According to Relevant Regulations
  • New Plaster and Tidying Up Afterwards

A partial house wiring service can be a challenge, as it can be difficult to identify the correct wires to replace among the existing wiring. A partial rewire is also only possible if your current electrical wiring can withstand the required electrical load. When a qualified electrician tests your wiring and the electrical system is struggling, we’ll have to consider a full rewire.
